Biological magnification, or biomagnification, occurs when pollutants taken up by organisms at the base of the food chain reach high concentrations in the bodies of animals at the top of the food chain. Effects of biomagnification vary widely depending on the pollutant, organism and ecosystem in question.

The Rod-Cone-Break is considered to be a d</span>ark environment adaptation function in the eye, wherein for an estimated time of the first ten minutes in the dark, the cones<span> needs less light to reach a threshold response than do the </span>rods<span>. Thereafter, the </span>rods<span> need less light. The point at which the </span>rods<span> become more sensitive is called the </span>rod-cone break<span>.</span>
